The human histamine receptors hH1R and hH2R constitute important drug targets, and hH3R and hH4R have substantial potential in this area. Considering the species-specificity of pharmacology of HxR orthologs, it is important to analyze hHxRs. Here, we summarize current knowledge of hHxRs endogenously expressed in human cells and hHxRs recombinantly expressed in mammalian and insect cells. We present the advantages and disadvantages of the various systems. We also discuss problems associated with the use of hHxRs antibodies, an issue of general relevance for G-protein-coupled receptors. There is much greater overlap in activity of “selective” ligands for other hHxRs than the cognate receptor subtype than generally appreciated. Studies with native and recombinant systems support the concept of ligand-specific receptor conformations, encompassing agonists and antagonists. It is emerging that for characterization of hHxR ligands, one cannot rely on a single test system and a single parameter. Rather, multiple systems and parameters have to be studied. Although such studies are time-consuming and expensive, ultimately, they will increase drug safety and efficacy.
